Michel Mayor has recently won a Noble Prize for his astounding work related to the research of exoplanets.
The acclaimed researchers made a surprising statement on the very next day after becoming a Nobel laureate, arguing that humanity will not be able to colonize exoplanets in the near future even if we manage to find some candidates who offer the same conditions encountered on Earth.
Distance is the primary obstacle which rules out such possibilities. Even if researchers manage to find a habitable planet situated at less than one hundred light-years away, we will need hundreds of millions of years to reach it with the technology which is now available.
As climate change continues to wreak havoc, the world some voices have argued that we can always move to another planet in case of a dire collapse. According to the researchers this is impossible since there is no way to reach those planets in time. More effort should be put into taking care of Earth and limiting the effects of pollution in the long run.
It is important to keep in mind the fact that this does not rule out the ambitions to colonize objectives that are closer to Earth, like the Moon and Mars. In recent years a large number of countries and enterprises have started to look at Mars at an excellent starting point for the ambition to explore the universe.
Many are working on technology that could be used to increase our chances of survival on the Red Planet. While the distance is relatively small the main problem is posed by the harsh conditions which can be encountered on the surface of the planet, among which we can count frigid temperatures and deadly cosmic radiation.
At some point, humanity could invent a new engine that may allow us to travel across the universe, but only time will tell.
